Can i use hydroquinone on my pubic area and my bikini line?

Yes, but be careful: Unfortunately it is not that easy getting rid of freckles, a genetic trait that is intensified by sun exposure. Some have freckle-like areas on their private as well and the otc bleaching cream such lustra (hydroquinone) may help. Chemical peels/laser treatments are more effective but often costly. You must minimize sun exposure otherwise it will re-darken. Consult doc. Good luck.
